On the development of a general algebraic modeling system in a strategic planning environment,ironment are examined. The resulting development of a General Algebraic Modeling System (GAMS) is described. The data structure of this system is analyzed in some detail, and comparisons to other modeling systems are made. Selected aspects of the language are presented. The paper concludes with a ca

The indus basin model: A special application of two-level linear programming,specification of surface and ground water related policies in Pakistan. It is also a special application of the two-level linear programming problem. The concept of multi-level programming is introduced, and the general two-level linear program is described as a non-convex problem. It is shown, howe

A theoretical model for the determination of the optimal design of a power transportation and distrn is restricted to a single voltage level and the problem is presented as a network capacity expansion model. In this paper we capitalize on notions used in standardization studies of electrical networks to arrive at an optimization model of the global transportation and distribution system. Several

Mathematical optimization versus practical performance: A case study based on the maximum entropy chich leaves one to wonder whether solving the mathematical optimization problem will help us in any way with our original practical problem. In many fields this is very difficult to evaluate..In this paper we pick a case study motivated by a problem in diagnostic medicine. A cross-section of the hum

An algorithm for optimum structural design using duality,h mathematical methods one must restrict the search to some subset of all possible structures..In this paper we restrict ourselves to consider the following problem: minimize the weight of a structure subject to given limitations on stresses and displacements under multiple load conditions.
